one of the three great schemes into which philosophy is divided in regard to the possibility of truth and the means of its attainment. The first scheme is that of skepticism or Pyrrhonism, which denies the possibility of truth altogether, and affirms that we are by the constitution of our being condemned to hopeless and helpless doubt. The second scheme is that of mysticism, which, admitting the deceptive nature of human reason, and the unsatisfactory character of all human inquiry, yet postulates the possibility of truth as attainable by a certain inspiration or intuition superior to reason. The third scheme, viz., that of dogmatism, asserts full confidence in the results of our intellectual faculties when duly exercised on objects within their grasp, and affirms the possibility of discovering truth by a proper attention to order, method, and the laws of our constitution.
